A Timely Reminder on Substantiation as ART Rejects $61K in WorkāRelated Expense Claims
The Administrative Review Tribunal (ART) has recently affirmed the ATOās decision to deny over $61,000 in workārelated expense deductions claimed by a taxpayer, highlighting how critical proper evidence is when lodging returns.
The taxpayer, an engineer working partly from home, claimed a range of deductionsāincluding car, travel, clothing, and home office expenses. The ART disallowed many of these due to inadequate substantiation.
Key issues included:
š Car expenses:
Logbooks were not kept contemporaneously and didnāt match independent records such as vehicle service documentation.
š Travel expenses:
Claims for taxi and rideshare trips lacked essential details (dates, times, destinations), and the taxpayer could not clearly distinguish reimbursed from unreimbursed travel.
š Home office expenses:
Only estimated businessāuse percentages were provided, without evidence of the actual utility costs. The ART also found the apportionment method neither fair nor reasonable.
š” Takeaway for taxpayers:
Workārelated expenses are only deductible when you can clearly demonstrate both eligibility and substantiation. Estimates without documentation are unlikely to withstand ATO scrutiny.
